In Arezzo we rushed up to Basilica of San Francesco - Romanesque style church in the center of the old city. In the Bacci di Lorenzo chapel we found what we were so much looking for: Legend of the True Cross series of Piero della Francesca frescoes. It is a collection of 1o big masterpieces made between 1452 and 1466. The most impressive are The adoration of the wood and The Battle of Constantine and Maxentius.
The structure of the paintings is clear and well organized. Perfectly used chromatic palette and chiaroscuro transform the paintings into the fantastic 3-dimensional images.
